Abstract

Procedure for the preparation of a reaction mixture obtained by nitration of aliphatic or cycloaliphatic ketones, if necessary in the presence of the corresponding alcohols, with nitric acid at least 95% by weight, in the presence of an inert organic solvent for the organic compounds characterized in that the reaction mixture is diluted with so much water that, before separation from the organic phase, it contains 10-70% by weight nitric acid, and the separated aqueous phase is extracted with an inert organic solvent .
